Not much to add from other posts, reloaded in an apartment for a year or so. Mounted everything to a cheap wood folding conference table you can buy at any office supply. Not the greatest thing, but worked.
Vibratory tumbler might be noisy enough to bug some people, depends more on how thin the walls are? I've never had any issues with the vibratory tumbler, but would be sure its on a solid surface during the hours you're not there to monitor it. Also, lock it down in some way, I found mine once laying on the floor making all kinds of racket, brass and corn cobb everywhere. Whoops! I put a T-Handle allen wrench through a hole on the base into the workbench to keep it on the bench now.
